Prorateer.com browser hijacker (virus) - Free Instructions

What is Prorateer.com browser hijacker?

Prorateer.com completely changes the user experience by messing up the browser settings

Prorateer.com is your new homepage if you have the extension

Prorateer.com is one of the thousands of browser hijackers that are created to track users' browsing activity and generate revenue with pay-per-click advertising.^[1] It changes the main settings, like the homepage, new tab address, and search engine to force users to perform searches through its websites.

Because the changes happen rather quickly and unexpectedly, many think that they have been infected with a virus. Although browser hijackers are not that dangerous in themselves, they can lead to more serious problems. The developers of such applications do not care about user privacy or security.

Browser extensions can take over all aspects of your browser and change what you see. You might receive inaccurate search results that lead to misinformation or dangerous pages where you could be tricked into providing your personal information or downloading PUPs and malware.^[2] This could even lead to financial losses or identity theft.^[3]

Browser plugin distribution techniques

Usually, the appearance of such extensions in the machine is the users' own fault. There is a common misconception among some people that the Internet is a completely safe space and viruses are a thing of the past. People often ignore security expert tips on how to keep yourself safe online and that later leads to problems like these.

So where can you find browser add-ons that hijack users' browsers? The answer is everywhere. That is why it is important to read everything you are given and not rush to click the buttons. We say that people should use only official web stores to get applications, but even they are not free from hijackers.

Most often developers use shady websites, deceptive ads to redirect users to their promotional sites, which then redirect to the chrome web store for example. Having an extension on that store is legitimate and trustworthy, but as we said, you should still read the reviews and see how many users it has. Look at the description and see if it looks true. Sometimes creators use big company names (for example “we partnered with Google to provide you with…”) to create even more trust and desirability.

Another very popular method is spreading software that can perform the changes. These are called potentially unwanted programs.^[4] They also can come disguised as handy tools, so users would want to download them. Another way is to have them distributed as bundled software on unofficial freeware^[5] sites.

The owners of such websites still need to make money so they include additional programs in the installers without disclosing it in the hopes that most users will not notice them. Unfortunately, that is exactly what happens most of the time, and when they get into the system, they start various processes in the background that can affect the PC.

Prorateer.com may track your browsing activity

This particular extension sets uk.prorateer.com as the homepage (your URL could differ depending on your location) and adds its own search engine. That is unusual for a browser hijacker as many of them implement already existing ones just to make them functional and serve their purpose. When you type something in the search box and press Enter, a lot of promotional links pop up and it is hard to see how that would be convenient for anyone.

Go to your browser settings

First, let's try to remove the extension, and see if that helps. You can do it via browser settings:

Google Chrome

• Open Google Chrome, click on the Menu (three vertical dots at the top-right corner) and select More tools > Extensions.
• In the newly opened window, you will see all the installed extensions. Uninstall all the suspicious plugins that might be related to the unwanted program by clicking Remove.

MS Edge:

1. Select Menu (three horizontal dots at the top-right of the browser window) and pick Extensions.
2. From the list, pick the extension and click on the Gear icon.

Scan your machine with professional security software

If you tried the first removal method, but it did not help and the settings changed back again, this is definitely a sign of a PUA hiding in your system. In that case, the application will keep messing up your browser until you completely remove it from your PC. Identifying the program responsible for hijacking your browser might be difficult if you have never done this before.

The program could be disguised as antivirus, video, or image editing software. If you do not want to risk deleting the wrong files, we suggest using SpyHunter 5Combo Cleaner or Malwarebytes professional security tools that will scan your machine, eliminate it, and prevent such infections in the future by giving you a warning before a PUP can make any changes.

If manual removal is what you still prefer, we have instructions for Windows and Mac machines:
